Find the Domain of the following exponential and logarithmic equations and solve them:
kakasveta [241]

The base of a logarithm should always be positive and can't be equal to 1, so the domain is 0 < <em>x</em> < 1 or <em>x</em> > 1.

\log_{\frac1x}243=5

Write both sides as powers of 1/<em>x</em> :

\left(\dfrac1x\right)^{\log_{\frac1x}243}=\left(\dfrac1x\right)^5

Recall that a^{\log_ab}=b, so that

243=\left(\dfrac1x\right)^5

243=\dfrac1{x^5}

x^5=\dfrac1{243}

Take the 5th root of both sides, recalling that 3⁵ = 243, so

x=\sqrt[5]{\dfrac1{243}}=\boxed{\dfrac13}

You have a summer job that pays you $5.60 an hour you get $8.40 an hour for overtime how many hours of overtime must you work to
Shtirlitz [24]

The following given problem can be expressed in the form of:

E = 5.60 * T1 + 8.40 * T2

 

where,

E = total earning

T1 = normal hours worked

T2 = overtime hours

 

Assuming that the maximum T1 hours is 40 hours. Beyond that is considered overtime, therefore:

 

287 = 5.60 * 40 + 8.40 * T2

T2 = 7.5 hours

 

<span>Therefore 7.50 overtime hours is needed.</span>
